DEVICE FOR MAKING BARBE D STRIPS FOR FENCES.

EPESIPICAIION forming part of Letters Patent No. 310,394, dated. January6, 1835.

Application filed August 15, i594.

all whom it may concern:

Be it known that I, J osmn W. Ems, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State of Pen 11-sylvania, have invented a new and improved barbed metallic strip or thinflexible rail for fences, and also a means for rapidly and cheaplymaking the same, of which the following is a specification.

My invention relates to that class of thin flexible metallic strips orrails which are provided along one or both edges with barbs or pointsintegral therewitlnand used to deter animals from breaking or pushingdown fences constructed of the same; and the improvement I have madeconsists of a thin metallic strip, of the form hereinafter described,divided 1ongitudinally by means of a rotating zigzagshaped sharpedgedoutting-disk, operatingin conjunction with a plain roll in such a manneras to slit the iron and form suitable barbs or angular points on eachhalf of the strip along its line of cut and separation, all of whichwill be readily understood from the following description, taken inconnection with the accompanying drawings, wherein- Figure 1 representsa front elevation of a stout frame containing a pair of rolls, one ofwhich is plain, and the other provided with a sharp zigzag-edgedcutting-disk of the character hereinbefore mentioned; Fig. 2, a transverse vertical section of the same, including the guide-box in front ofthe rolls and receiving-plate behind them; Fig. 3, a vertical sec tionof the cutterroll with a portion of its shaft therein; Fig. 4, a portionof a plain thin strip of metal; Fig. 5, a similar strip of metal uponwhich is delineated the proposed zigzag out or line of separation. Fig.6 represents one half of said strip, which is divided from the otherhalf in such a manner as to form a series of sharp angular points alongone edge thereof; Fig. 7, a portion of a ribbon or strip of metal,having along each side thereof a single l1alfround raised bead or rib soarranged upon the strip as that the reverse side, or that por tion ofthe strip directly opposite each rib or half-round bead, shall present aflat and plain surface; Fig. 8, a twisted longitudinal half of saidmetallic strip, having a half-round rib or raised bead along and uponone side only, and

with closely-connected angular points or barbs along one edge, wherebyit is made suitable for fencing purposes.

To put my invention into practice, and thereby make barbed metallicflexible rails or fencin g-strips of the character hereinafterset forth,I provide a suitable frame, A, and place therein a pair of strong rolls,a a, each consisting of a shaft, 1), upon which is arranged and affixeda steel disk, 0, supported sidewise by stiff circular flanges. The faceof the under roll, a, is plain and cylindrical, or parallel with itsaxis, or nearly so, being varied in that respect by its central disk, 0,which is a little larger than its side supports. The disk 0 of the upperroll, a, also projects outward beyond the immediate face of its sideflanges, (Z, a distance equal to the thickness of such metallic stripsit is intended to operate on, and is provided with a connected and solidseries of V-shaped chisels, f, integral there: with, that together forma continuous sharp cutting-edgeextending completely around its peripheryon a zigzag line, which is arranged directly over and as close to theplain face of the lower roll, 0, as may be without actual contacttherewith, being adjustable in that relation by means of vertical screwsg in the top of the frame A, whereby any passing strip may be divided orsplit longitudinally and not injure or spoil the cutters. The sideflanges, d, of the upper roll, a, by a sudden increase of diameter at aproper distance from the cut tingdisk, form collars ii, that overlap theedges of the lower roll in such a manner as to prevent independentend-play or shifting of 4 relative positions.

Attached to the front of the frame A is a suitable guide-box, B, as ameans for the proper introduction of metallic ribbons or strips to thejoint action of the rolls; and at the rear of the frame A and oppositeside of the rolls is a small table, D, for temporarily supporting thestrip after being acted on. This construction of machine is very simpleand substantial, and calculated to do the work required of it in a veryrapid and satisfactory manner; and as the disks, with their sideflanges, are readily detachable from the shafts, they can be removed forthe purpose of sharpening, rehardening, or the substitution of new i I iverse] y to its length until its angular barbs I;

ones when and as the case may require. After the rolls have beenproperly adjusted and set in motion a strip of metal of suitable length.breadth, and thickness maybe intrqduced end foremost through theguide-box B to the rolls, whereupon it will be seized by them, carriedalong, and divided longitudinally in such a manner as to produce andform along its line of cut a connected series of angular teeth orsharp-pointed barbs.

Although I have shown in the drawings, Figs. 4-, 5, and 6, a plain stripof metal and the effect produced thereon by the rolls, yet I prefer touse a special strip, E, having one single'half-round rib or raised bead,1', along each side thereof, not opposite one another, but so located asto be widely separate, so that the portion of the strip directly undereach rib i shall present a perfectly plain sznooth surface, havingnearly tlnee-t'ourths of its entire width on one side of the rib andonefourth on the other side, which shape is easier formed, is lighter,and much more flexible than when the ribs join. It also possesses thatquality admitting of uniform and symmetrical twist without unduecontortion or strain. This ribbed st rip E, when of proper size, andpreferably cold, is to be entered end foremost through the guidebox B tothe revolving rolls, which will split, divide, and separate itlongitudinally in such a manner as to leave each part with a'peri'eetlyplain side, and its opposite with a central rib, i, thereon, and oneedge of the strip with a series of closely-studded triangular-shapedpoints, serrations, or barbs, 7;, after which each section or rail soproduced and formed is to be twisted trans are disposed and arrangedspirally all around it, and the rib is caused to appear first on oneside and then on the other at regular intervals, by which a novel effectis created.

Having thus described my improved metallic barbed fence-rail, Iclain1- 1. In a machine for forming barbed metallic rails or flexiblestrips for fencing, a circular disk provided with a connected. series ofintegral zigzag-shaped sharp cutting-edges, in combination with aplain-faced roll.

2. In a machine for forming barbed metallic rails or flexible strips forfencing, a detachable circular disk provided with a series of zigzagsharp cutting-edges integral therewith, and a flange on each side of thedisk, in combination with a plain-faced roll.

3. In a machine for forming barbed metallic rails or flexible strips forfencing, a circular disk provided with a connected series ofzigzagshapcd cutting-edges, made adjustable up or down in a frame, incombination with its side supportingflanges and a plain-faced roll.

In a machine for forming barbed metallic rails or flexible strips forfencing, a circular disk provided with a series of zigzag cutting-edges,in combination with a plain-faced roll and a guide-box leading to thespace between them.

In a machine for forming barbed metallic rails or flexible strips forfencing, acircular disk provided with a continuous zigzag cutting-edgethat is supported on each side by a flange, in combination with a rollcontain ing a detachable plain faced disk arranged in close proximity tothe cutting-disk, and operating jointly in such a manner as to severstrips of metal entered between them.

6. In a machine for forming barbed metallic rails or flexible strips forfencing, a circular disk provided with a sharp zigzag cuttingedge, incombination with a plain-laced roll, working in conjunction with thecutting-disk to sever strips of metal in such a manner as to leave sharpangular points on each along the line of cut and separation, a guide-boxfor properly directing such strips of metal to the cutting action of thesharp-edged disk, a table for receiving the strips after being cut, anda means for adjusting the cutting-disk toward and from the plain-facedroll.
